    The role of volcanic and anthropogenic activities in controlling the erosion processes at Vulcano island (Italy) (2011)
    Comitato Glaciologico Italiano
    Details
    Publication Date: 2017-04-04
    Description: The paper describes the erosion processes acting at La Fossa cone (Vulcano Island, Italy). La Fossa cone is a stratovolcano made up of pyroclastic deposits and lavas covered by tuffs from the last eruption, dated 1888-90. Its flanks are affected by intense water erosion phenomena leading to the formation of denudation surfaces due to sheet erosion, rills, gullies and small canyons. As a consequence of very intense rainfalls, episodic debris flows occur along main gullies and canyons. Fumarolic activity plays an important role in the control of erosion processes, being both an obstacle for the growth of vegetation and a weathering factor. The GIS analysis and comparison of geo-referenced maps and aerial photos highlighted the influence of man-made structures on erosion processes, with particular reference to deep modifications in the natural stream network induced by buildings and roads. The combined effects of volcanic and anthropogenic activities, together with the additional role played by the strong inter-annual variability of rainfall amounts and intensities, give rise to significant changes in water erosion rates. A total volume of 5,700 m3 of volcanic products eroded between the years 1980 and 2008 from the upper portion of La Fossa cone has been estimated by GIS analysis.

    L'area delle risorgive nel sistema insediativo mesolitico: alcuni esempi dal pordenonese (2011)
    Museo Friulano di Storia Naturale
    Details
    Publication Date: 2017-04-04
    Description: The authors present the work undertaken on the lithic material collected in the spring area between Orcenico Superiore and Savorgnano (Pordenone-Italy). The sites are located on an NE-SW elongated Lateglacial gravel ridge, which to the present day is to be considered a stable area (i.e. preserved from alluvial and erosive action of Tagliamento and Meduna rivers). Different periods are represented in the lithic industries, spanning from the Mesolithic to the Bronze Age. This paper presents the results of the study carried out on the Mesolithic industries, mainly to be ascribed to the Castelnovian tradition. The typological composition of the assemblages shows different activities which could be associated with residential camps, without any particular specialization although this kind of interpretation could be biased by the non systematic nature of the findings. Different operational chains were in place, aiming to produce either bladelets or flakes. Raw materials are mostly of local origin, although few pieces were brought in from the Prealps, showing a North-South mobility along river routes. At the same time, there are scarce lithic materials imported from the upper part of the Udine plain, which is rich in good quality flint pebbles. Further technological and typological differences show a rather neat separation between sites on either sides of Tagliamento river. When we consider the distribution of Mesolithic sites in Friuli, a logistical settlement system seems to emerge: bigger sites are located at the edge of ecologically differentiated areas in connection with stable water sources such as the spring area between Orcenico and S. Vito al Tagliamento and the piedmont; complementary to those, task-related short-term sites characterised by less materials and fewer lithic types are found in the Prealps at middle altitude.

    The Kamil Crater in Egypt (2010)
    American Association for the Advancement of Science
    Details
    Publication Date: 2020-12-21
    Description: BREVIA
    Description: We report on the discovery in southern Egypt of an impact crater 45 m in diameter with a pristine rayed structure. Such pristine structures have been previously observed only on atmosphereless rocky or icy planetary bodies in the Solar System. This feature and the association with an iron meteorite impactor and shock metamorphism provides a unique picture of small-scale hypervelocity impacts on the Earth's crust. Contrary to current geophysical models, ground data indicate that iron meteorites with masses of the order of tens of tons can penetrate the atmosphere without significant fragmentation.

    Morphostructural setting of the Sangro and Volturno Rivers divide area (Central-Southern Apennines, Italy) (2008)
    Comitato Glaciologico Italiano
    Details
    Publication Date: 2021-04-07
    Description: Topography of the Apennines chain resulted from the combined action of tectonic displacements (related to thrusting and high-angle faulting), large-scale uplift and surface processes. In such mountainous settings, where strong erosion is often responsible for incomplete stratigraphic records of surface evolution of thrust belts, geomorphological analysis helps quantify these processes and provide a framework for interpreting the geologic history of these regions. We studied a 400 km2 area of the Central-Southern Apennines, covering Abruzzo, Lazio and Molise regions, by means of morphostructural analysis. This sector of the chain emerged during the Lower Pliocene and suffered a long-lasting erosion. Our study reveals a high relief landscape dominated by high-standing, resistant carbonates forming structure-controlled landforms (morphosculptures), and valleys underlain by erodible siliciclastics. Quaternary deposits are few and scattered, and they give poor constraints for the recognition of ancient base-levels. However, this study defines and identifies several upland erosional surfaces (paleosurfaces) that may be linked to ancient base-levels. On the basis of cross-cut relationships between paleosurfaces and structural landforms, we outlined a possible long-term geomorphological evolution of the study area. Most of the local tectonic displacements in this sector of the chain took place during Miocene and Pliocene, by means of thrusting and strike-slip faulting, whereas only localized extensional tectonics occurred during Quaternary times. Since the Pliocene, differential erosion promoted exhumation of carbonates and deep incision of pre-existing erosional surfaces. This strong erosion can be related to a regional base-level lowering promoted by large-scale uplift of the axial sector of the Central-Southern Apennines.

    Time-resolved seismic tomography detects magma intrusions at Mt. Etna (2007)
    American Association for the Advancement of Science
    Details
    Publication Date: 2017-04-04
    Description: The continuous volcanic and seismic activity at Mount Etna makes this volcano an important laboratory for seismological and geophysical studies. We used repeated three-dimensional tomography to detect variations in elastic parameters during different volcanic cycles, before and during the October 2002–January 2003 flank eruption. Well-defined anomalous low P- to S-wave velocity ratio volumes were revealed. Absent during the pre-eruptive period, the anomalies trace the intrusion of volatile-rich (Q4 weight percent) basaltic magma, most of which rose up only a few months before the onset of eruption. The observed time changes of velocity anomalies suggest that four-dimensional tomography provides a basis for more efficient volcano monitoring and shortand midterm eruption forecasting of explosive activity.
